Replacement for TDA0161 metal detection IC?

(1/1)

BreakingOhmsLaw:
Hey everyone,

Does anyone have recommendation to replace a TDA0161?

The application is to detect a metal locking pin that goes into a hole. The hole has in integrated coil, so the pin changes its inductance when present.
Simple metal detection really. I'm having a hard time finding a simple replacement.

you may get some hits, and maybe some possible fakes too ? and maybe some absurd pricing too ?

BreakingOhmsLaw:
Thanks, but I'm looking for an active chip, as this is for a new product.
Anyway, I'm now going with the Texas Instruments LDC series, the are "Inductance to digital" converters and are reasonably priced.
